A new equalization technique for Multi-h CPM in a telemetry multipath channel

A decision-feedback equalizer (DFE) for Multi-h CPM in aeronautical telemetry is presented in this paper. This algorithm estimates the inter-symbol interference and cancels it from the samples used to make the bit decisions. The approach improves the bit estimates sequentially, thereby increasing the probability of obtaining accurate estimates. Simulation results show an 1 dB improvement in bit error rate performance than the MMSE-equalizer for Multi-h CPM in a multipath channel environment.
